HOW IT FEELS/SMELLS/LOOKS:This defrizzer, which bears the brand's famed tropical-musk scent, has a dry oil-like texture and a slight stickiness.

WHY WE LIKE IT:The spray tackles frizz, flyaways, static, and split ends and leaves hair glossy no matter the forecast. It can exacerbate greasiness, so if you've got an oily scalp, be sure to keep it far from the roots—just spritz onto hands and run them through hair.
